GUTTER LOCATION The traditional way to mark gut- ter layout is to use a chalk line. First, safely position the ladder on even ground with the ladder stabi- lizer firmly supported by the roof deck. At one corner of the fascia, mark the highest point of the gut- ter run 1-1/4 in. below the drip- edge flashing. Unreel the chalk line and move the gutter to the opposite end of the fascia. At that corner, first level the string, and then drop the downspout end about 1 inch per 20 feet and snap the chalk line. This achieves a slope that helps gravity pull water to the downspout locations. (Gutters longer than 35 feet should have a downspout at each end, pitching the gutter from the center to each downspout.) INSTALLATION Pre-attach the hidden hangers to the gutter by clipping them in place every couple of feet along the length of the section. Make sure to locate a fastener near the end of each section to minimize stress at the joint locations. If you do not have a solid wood fascia to hold the fasteners, you will need to locate the rafter tails. These 2-by framing members should be located every 16 inch- es behind the fascia. Mark the tails along the chalk line and
A chalk line is a traditional tool for marking the layout line for gutter installation, but for this carport gutter we used a laser level along the fascia.
Cuts can be made using hacksaw or a 12” miter saw with the blade turned backward. Cut the gutter upside-down. Use gutter screws combined with hidden bracket fasteners. Space the fasteners along the gutter no more than 2’ apart.
